: Systems like those from IPG Automotive use "Software-in-the-Loop" (SiL) and "Hardware-in-the-Loop" (HiL) to validate ECU performance against virtual driving models.
The era of swapping parts to fix steering is over. Electric Power Steering is a closed-loop control system, not a hydraulic circuit. A multimeter tells you if power is present. A test light tells you if a circuit is complete. But only dedicated tell you if the torque sensor is lying, the motor is cogging, or the ECU has lost its mind. eps testing tools
These are the workhorses. A bi-directional scanner doesn't just read codes; it talks back to the EPS module. : Systems like those from IPG Automotive use
Regardless of the software used, specific testing methodologies are applied to ensure data integrity. A multimeter tells you if power is present
: Units like the EPS Testing Master System from ATG allow for testing over 300 different steering units by simulating real-road loads.
